5. In an injector, the combination with a Water receiving chamber having steam -injecting tubes therein, of a communicating chamber having an overiiow-pipe connected therewith, and provided with integral hooked bearings, a check-valve pivotally hung upon the hooked bearings and adapted to be detached therefrom, a nozzle mounted in the communicating chamber and provided with a spring-pressed valve to control the ow ot Water to the chamber and overflow-pipe, substantially as described.
